New Zealand's war dance, the haka, was composed by the Maori tribe Ngati Toa's warrior chief Te Rauparaha in the early 19th century to celebrate the fiery warrior's escape from death in battle.

It was New Zealand's All Blacks rugby team who made it world famous, performing the traditional dance spectacle before matches.

Some view the eyeballing routine as an unsporting attempt to intimidate the opposition before the match begins.

Not all opposition players embrace it. The 1996 Wallabies team chose to turn their backs on the haka and warm up in their own half before a clash in Wellington, an idea that backfired with a record 43-6 defeat.

In 2008, Welsh players showed their disdain when at the end of the haka they refused to break from their linked arms and start the game. Instead, they stood, holding their opponents' gaze for two minutes, trying to stare down the All Blacks.
